net_tstamp: define new flag HWTSTAMP_FLAG_BONDED_PHC_INDEX

As we defined the new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX as enum, it's not easy for userspace program to check if the flag is supported when build. Let's define the new flag so user space could build it on old kernel with ifdef check.
